DESCRIPTION OF EMBODIMENTS

The following description sets forth exemplary methods, parameters and the like. It should be recognized, however, that such description is not intended as a limitation on the scope of the present disclosure but is instead provided as a description of exemplary embodiments.

As discussed above, a user may wish to access various user interfaces for using different functions on a portable multifunction device. Providing functionalities for accessing such user interfaces without relying solely on displayed icons may be beneficial for multifunction devices of any size by freeing the display for other features or aspects. Other input mechanisms such as buttons may these additional functionalities, but it is highly desirable for such input mechanisms to be intuitive (since their appearance typically does not change as readily as a displayed object) and to allow for multifunctional use. Combinations of hardware buttons and rotatable and depressible input mechanisms that are multifunctional alone and in combination are highly desirable for providing different user interfaces on a portable multifunction device.

Below, FIGS. 1A-1B, 2, 3, 4A-4B, and 5A-5B provide a description of exemplary devices for performing the techniques for button functionalities for user interfaces. FIGS. 6-12 illustrate exemplary button functionalities for user interfaces. The user interfaces in the figures are also used to illustrate the processes described below, including the processes in FIGS. 13-20 .

Although the following description uses terms “first,” “second,” etc. to describe various elements, these elements should not be limited by the terms. These terms are only used to distinguish one element from another. For example, a first touch could be termed a second touch, and, similarly, a second touch could be termed a first touch, without departing from the scope of the various described embodiments. The first touch and the second touch are both touches, but they are not the same touch.

The terminology used in the description of the various described embodiments herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used in the description of the various described embodiments and the appended claims, the singular forms “a”, “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It will be further understood that the terms “includes,” “including,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

The term “if” may be construed to mean “when” or “upon” or “in response to determining” or “in response to detecting,” depending on the context. Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” may be construed to mean “upon determining” or “in response to determining” or “upon detecting [the stated condition or event]” or “in response to detecting [the stated condition or event],” depending on the context.

Embodiments of electronic devices, user interfaces for such devices, and associated processes for using such devices are described. In some embodiments, the device is a portable communications device, such as a mobile telephone, that also contains other functions, such as PDA and/or music player functions. Exemplary embodiments of portable multifunction devices include, without limitation, the iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, Calif. Other portable electronic devices, such as laptops or tablet computers with touch-sensitive surfaces (e.g., touch screen displays and/or touchpads), are, optionally, used. It should also be understood that, in some embodiments, the device is not a portable communications device, but is a desktop computer with a touch-sensitive surface (e.g., a touch screen display and/or a touchpad).

In the discussion that follows, an electronic device that includes a display and a touch-sensitive surface is described. It should be understood, however, that the electronic device optionally includes one or more other physical user-interface devices, such as a physical keyboard, a mouse, and/or a joystick.

The device may support a variety of applications, such as one or more of the following: a drawing application, a presentation application, a word processing application, a website creation application, a disk authoring application, a spreadsheet application, a gaming application, a telephone application, a video conferencing application, an e-mail application, an instant messaging application, a workout support application, a photo management application, a digital camera application, a digital video camera application, a web browsing application, a digital music player application, and/or a digital video player application.

The various applications that are executed on the device optionally use at least one common physical user-interface device, such as the touch-sensitive surface. One or more functions of the touch-sensitive surface as well as corresponding information displayed on the device are, optionally, adjusted and/or varied from one application to the next and/or within a respective application. In this way, a common physical architecture (such as the touch-sensitive surface) of the device optionally supports the variety of applications with user interfaces that are intuitive and transparent to the user.

Attention is now directed toward embodiments of portable devices with touch-sensitive displays. FIG. 1A is a block diagram illustrating portable multifunction device 100 with touch-sensitive display system 112 in accordance with some embodiments. Touch-sensitive display 112 is sometimes called a “touch screen” for convenience and is sometimes known as or called a “touch-sensitive display system.” Device 100 includes memory 102 (which optionally includes one or more computer-readable storage mediums), memory controller 122, one or more processing units (CPUs) 120, peripherals interface 118, RF circuitry 108, audio circuitry 110, speaker 111, microphone 113, input/output (I/O) subsystem 106, other input control devices 116, and external port 124. Device 100 optionally includes one or more optical sensors 164. Device 100 optionally includes one or more contact intensity sensors 165 for detecting intensity of contacts on device 100 (e.g., a touch-sensitive surface such as touch-sensitive display system 112 of device 100). Device 100 optionally includes one or more tactile output generators 167 for generating tactile outputs on device 100 (e.g., generating tactile outputs on a touch-sensitive surface such as touch-sensitive display system 112 of device 100 or touchpad 355 of device 300). These components optionally communicate over one or more communication buses or signal lines 103.

As used in the specification and claims, the term “intensity” of a contact on a touch-sensitive surface refers to the force or pressure (force per unit area) of a contact (e.g., a finger contact) on the touch-sensitive surface, or to a substitute (proxy) for the force or pressure of a contact on the touch-sensitive surface. The intensity of a contact has a range of values that includes at least four distinct values and more typically includes hundreds of distinct values (e.g., at least 256). Intensity of a contact is, optionally, determined (or measured) using various approaches and various sensors or combinations of sensors. For example, one or more force sensors underneath or adjacent to the touch-sensitive surface are, optionally, used to measure force at various points on the touch-sensitive surface. In some implementations, force measurements from multiple force sensors are combined (e.g., a weighted average) to determine an estimated force of a contact. Similarly, a pressure-sensitive tip of a stylus is, optionally, used to determine a pressure of the stylus on the touch-sensitive surface. Alternatively, the size of the contact area detected on the touch-sensitive surface and/or changes thereto, the capacitance of the touch-sensitive surface proximate to the contact and/or changes thereto, and/or the resistance of the touch-sensitive surface proximate to the contact and/or changes thereto are, optionally, used as a substitute for the force or pressure of the contact on the touch-sensitive surface. In some implementations, the substitute measurements for contact force or pressure are used directly to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is described in units corresponding to the substitute measurements). In some implementations, the substitute measurements for contact force or pressure are converted to an estimated force or pressure, and the estimated force or pressure is used to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is a pressure threshold measured in units of pressure). Using the intensity of a contact as an attribute of a user input allows for user access to additional device functionality that may otherwise not be accessible by the user on a reduced-size device with limited real estate for displaying affordances (e.g., on a touch-sensitive display) and/or receiving user input (e.g., via a touch-sensitive display, a touch-sensitive surface, or a physical/mechanical control such as a knob or a button).

As used in the specification and claims, the term “tactile output” refers to physical displacement of a device relative to a previous position of the device, physical displacement of a component (e.g., a touch-sensitive surface) of a device relative to another component (e.g., housing) of the device, or displacement of the component relative to a center of mass of the device that will be detected by a user with the user's sense of touch. For example, in situations where the device or the component of the device is in contact with a surface of a user that is sensitive to touch (e.g., a finger, palm, or other part of a user's hand), the tactile output generated by the physical displacement will be interpreted by the user as a tactile sensation corresponding to a perceived change in physical characteristics of the device or the component of the device. For example, movement of a touch-sensitive surface (e.g., a touch-sensitive display or trackpad) is, optionally, interpreted by the user as a “down click” or “up click” of a physical actuator button. In some cases, a user will feel a tactile sensation such as an “down click” or “up click” even when there is no movement of a physical actuator button associated with the touch-sensitive surface that is physically pressed (e.g., displaced) by the user's movements. As another example, movement of the touch-sensitive surface is, optionally, interpreted or sensed by the user as “roughness” of the touch-sensitive surface, even when there is no change in smoothness of the touch-sensitive surface. While such interpretations of touch by a user will be subject to the individualized sensory perceptions of the user, there are many sensory perceptions of touch that are common to a large majority of users. Thus, when a tactile output is described as corresponding to a particular sensory perception of a user (e.g., an “up click,” a “down click,” “roughness”), unless otherwise stated, the generated tactile output corresponds to physical displacement of the device or a component thereof that will generate the described sensory perception for a typical (or average) user.

It should be appreciated that device 100 is only one example of a portable multifunction device, and that device 100 optionally has more or fewer components than shown, optionally combines two or more components, or optionally has a different configuration or arrangement of the components. The various components shown in FIG. 1A are implemented in hardware, software, or a combination of both hardware and software, including one or more signal processing and/or application-specific integrated circuits.

Audio circuitry 110, speaker 111, and microphone 113 provide an audio interface between a user and device 100. Audio circuitry 110 receives audio data from peripherals interface 118, converts the audio data to an electrical signal, and transmits the electrical signal to speaker 111. Speaker 111 converts the electrical signal to human-audible sound waves. Audio circuitry 110 also receives electrical signals converted by microphone 113 from sound waves. Audio circuitry 110 converts the electrical signal to audio data and transmits the audio data to peripherals interface 118 for processing. Audio data may be retrieved from and/or transmitted to memory 102 and/or RF circuitry 108 by peripherals interface 118. In some embodiments, audio circuitry 110 also includes a headset jack (e.g., 212, FIG. 2 ). The headset jack provides an interface between audio circuitry 110 and removable audio input/output peripherals, such as output-only headphones or a headset with both output (e.g., a headphone for one or both ears) and input (e.g., a microphone).

I/O subsystem 106 couples input/output peripherals on device 100, such as touch screen 112 and other input control devices 116, to peripherals interface 118. I/O subsystem 106 optionally includes display controller 156, optical sensor controller 158, intensity sensor controller 159, haptic feedback controller 161, and one or more input controllers 160 for other input or control devices.

In some alternate embodiments, input controller(s) 160 are, optionally, coupled to any (or none) of the following: a keyboard, an infrared port, a USB port, and a pointer device such as a mouse. The one or more buttons (e.g., 208, FIG. 2 ) optionally include an up/down button for volume control of speaker 111 and/or microphone 113. The one or more buttons optionally include a push button (e.g., 206, FIG. 2 ).

A quick press of the push button may disengage a lock of touch screen 112 or begin a process that uses gestures on the touch screen to unlock the device, as described in U.S. patent application Ser. No. 11/322,549, “Unlocking a Device by Performing Gestures on an Unlock Image,” filed Dec. 23, 2005, U.S. Pat. No. 7,657,849, which is hereby incorporated by reference in its entirety. A longer press of the push button (e.g., 206) may turn power to device 100 on or off. The user may be able to customize a functionality of one or more of the buttons. Touch screen 112 is used to implement virtual or soft buttons and one or more soft keyboards.

Touch-sensitive display 112 provides an input interface and an output interface between the device and a user. Display controller 156 receives and/or sends electrical signals from/to touch screen 112. Touch screen 112 displays visual output to the user. The visual output may include graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output may correspond to user-interface objects.

Touch screen 112 has a touch-sensitive surface, sensor, or set of sensors that accepts input from the user based on haptic and/or tactile contact. Touch screen 112 and display controller 156 (along with any associated modules and/or sets of instructions in memory 102) detect contact (and any movement or breaking of the contact) on touch screen 112 and convert the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages, or images) that are displayed on touch screen 112. In an exemplary embodiment, a point of contact between touch screen 112 and the user corresponds to a finger of the user.

Touch screen 112 may use LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies may be used in other embodiments. Touch screen 112 and display controller 156 may detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch screen 112. In an exemplary embodiment, projected mutual capacitance sensing technology is used, such as that found in the iPhone® and iPod Touch® from Apple Inc. of Cupertino, Calif.

A touch-sensitive display in some embodiments of touch screen 112 may be analogous to the multi-touch sensitive touchpads described in the following U.S. Pat. No. 6,323,846 (Westerman et al.), U.S. Pat. No. 6,570,557 (Westerman et al.), and/or U.S. Pat. No. 6,677,932 (Westerman), and/or U.S. Patent Publication 2002/0015024A1, each of which is hereby incorporated by reference in its entirety. However, touch screen 112 displays visual output from device 100, whereas touch-sensitive touchpads do not provide visual output.

A touch-sensitive display in some embodiments of touch screen 112 may be as described in the following applications: (1) U.S. patent application Ser. No. 11/381,313, “Multipoint Touch Surface Controller,” filed May 2, 2006; (2) U.S. patent application Ser. No. 10/840,862, “Multipoint Touchscreen,” filed May 6, 2004; (3) U.S. patent application Ser. No. 10/903,964, “Gestures For Touch Sensitive Input Devices,” filed Jul. 30, 2004; (4) U.S. patent application Ser. No. 11/048,264, “Gestures For Touch Sensitive Input Devices,” filed Jan. 31, 2005; (5) U.S. patent application Ser. No. 11/038,590, “Mode-Based Graphical User Interfaces For Touch Sensitive Input Devices,” filed Jan. 18, 2005; (6) U.S. patent application Ser. No. 11/228,758, “Virtual Input Device Placement On A Touch Screen User Interface,” filed Sep. 16, 2005; (7) U.S. patent application Ser. No. 11/228,700, “Operation Of A Computer With A Touch Screen Interface,” filed Sep. 16, 2005; (8) U.S. patent application Ser. No. 11/228,737, “Activating Virtual Keys Of A Touch-Screen Virtual Keyboard,” filed Sep. 16, 2005; and (9) U.S. patent application Ser. No. 11/367,749, “Multi-Functional Hand-Held Device,” filed Mar. 3, 2006. All of these applications are incorporated by reference herein in their entirety.

Touch screen 112 may have a video resolution in excess of 100 dpi. In some embodiments, the touch screen has a video resolution of approximately 160 dpi. The user may make contact with touch screen 112 using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which can be less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user.

In some embodiments, in addition to the touch screen, device 100 may include a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad may be a touch-sensitive surface that is separate from touch screen 112 or an extension of the touch-sensitive surface formed by the touch screen.

Device 100 also includes power system 162 for powering the various components. Power system 162 may include a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices.

Device 100 may also include one or more optical sensors 164. FIG. 1A shows an optical sensor coupled to optical sensor controller 158 in I/O subsystem 106. Optical sensor 164 may include charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor 164 receives light from the environment, projected through one or more lenses, and converts the light to data representing an image. In conjunction with imaging module 143 (also called a camera module), optical sensor 164 may capture still images or video. In some embodiments, an optical sensor is located on the back of device 100, opposite touch screen display 112 on the front of the device so that the touch screen display may be used as a viewfinder for still and/or video image acquisition. In some embodiments, an optical sensor is located on the front of the device so that the user's image may be obtained for video conferencing while the user views the other video conference participants on the touch screen display. In some embodiments, the position of optical sensor 164 can be changed by the user (e.g., by rotating the lens and the sensor in the device housing) so that a single optical sensor 164 may be used along with the touch screen display for both video conferencing and still and/or video image acquisition.

Device 100 optionally also includes one or more contact intensity sensors 165. FIG. 1A shows a contact intensity sensor coupled to intensity sensor controller 159 in I/O subsystem 106. Contact intensity sensor 165 optionally includes one or more piezoresistive strain gauges, capacitive force sensors, electric force sensors, piezoelectric force sensors, optical force sensors, capacitive touch-sensitive surfaces, or other intensity sensors (e.g., sensors used to measure the force (or pressure) of a contact on a touch-sensitive surface). Contact intensity sensor 165 receives contact intensity information (e.g., pressure information or a proxy for pressure information) from the environment. In some embodiments, at least one contact intensity sensor is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system 112). In some embodiments, at least one contact intensity sensor is located on the back of device 100, opposite touch screen display 112, which is located on the front of device 100.

Device 100 may also include one or more proximity sensors 166. FIG. 1A shows proximity sensor 166 coupled to peripherals interface 118. Alternately, proximity sensor 166 may be coupled to input controller 160 in I/O subsystem 106. Proximity sensor 166 may perform as described in U.S. patent application Ser. No. 11/241,839, “Proximity Detector In Handheld Device”; Ser. No. 11/240,788, “Proximity Detector In Handheld Device”; Ser. No. 11/620,702, “Using Ambient Light Sensor To Augment Proximity Sensor Output”; Ser. No. 11/586,862, “Automated Response To And Sensing Of User Activity In Portable Devices”; and Ser. No. 11/638,251, “Methods And Systems For Automatic Configuration Of Peripherals,” which are hereby incorporated by reference in their entirety. In some embodiments, the proximity sensor turns off and disables touch screen 112 when the multifunction device is placed near the user's ear (e.g., when the user is making a phone call).

Device 100 optionally also includes one or more tactile output generators 167. FIG. 1A shows a tactile output generator coupled to haptic feedback controller 161 in I/O subsystem 106. Tactile output generator 167 optionally includes one or more electroacoustic devices such as speakers or other audio components and/or electromechanical devices that convert energy into linear motion such as a motor, solenoid, electroactive polymer, piezoelectric actuator, electrostatic actuator, or other tactile output generating component (e.g., a component that converts electrical signals into tactile outputs on the device). Contact intensity sensor 165 receives tactile feedback generation instructions from haptic feedback module 133 and generates tactile outputs on device 100 that are capable of being sensed by a user of device 100. In some embodiments, at least one tactile output generator is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system 112) and, optionally, generates a tactile output by moving the touch-sensitive surface vertically (e.g., in/out of a surface of device 100) or laterally (e.g., back and forth in the same plane as a surface of device 100). In some embodiments, at least one tactile output generator sensor is located on the back of device 100, opposite touch screen display 112, which is located on the front of device 100.

Device 100 may also include one or more accelerometers 168. FIG. 1A shows accelerometer 168 coupled to peripherals interface 118. Alternately, accelerometer 168 may be coupled to an input controller 160 in I/O subsystem 106. Accelerometer 168 may perform as described in U.S. Patent Publication No. 20050190059, “Acceleration-based Theft Detection System for Portable Electronic Devices,” and U.S. Patent Publication No. 20060017692, “Methods And Apparatuses For Operating A Portable Device Based On An Accelerometer,” both of which are incorporated by reference herein in their entirety. In some embodiments, information is displayed on the touch screen display in a portrait view or a landscape view based on an analysis of data received from the one or more accelerometers. Device 100 optionally includes, in addition to accelerometer(s) 168, a magnetometer (not shown) and a GPS (or GLONASS or other global navigation system) receiver (not shown) for obtaining information concerning the location and orientation (e.g., portrait or landscape) of device 100.

In some embodiments, the software components stored in memory 102 include operating system 126, communication module (or set of instructions) 128, contact/motion module (or set of instructions) 130, graphics module (or set of instructions) 132, text input module (or set of instructions) 134, Global Positioning System (GPS) module (or set of instructions) 135, and applications (or sets of instructions) 136. Furthermore, in some embodiments, memory 102 (FIG. 1A) or 370 (FIG. 3 ) stores device/global internal state 157, as shown in FIGS. 1A and 3 . Device/global internal state 157 includes one or more of: active application state, indicating which applications, if any, are currently active; display state, indicating what applications, views or other information occupy various regions of touch screen display 112; sensor state, including information obtained from the device's various sensors and input control devices 116; and location information concerning the device's location and/or attitude.

Operating system 126 (e.g., Darwin, RTXC, LINUX, UNIX, OS X, iOS, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components.

Communication module 128 facilitates communication with other devices over one or more external ports 124 and also includes various software components for handling data received by RF circuitry 108 and/or external port 124. External port 124 (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with, the 30-pin connector used on iPod® (trademark of Apple Inc.) devices.

Contact/motion module 130 optionally detects contact with touch screen 112 (in conjunction with display controller 156) and other touch-sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module 130 includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred (e.g., detecting a finger-down event), determining an intensity of the contact (e.g., the force or pressure of the contact or a substitute for the force or pressure of the contact), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Contact/motion module 130 receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, optionally includes determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations are, optionally, applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, contact/motion module 130 and display controller 156 detect contact on a touchpad.

In some embodiments, contact/motion module 130 uses a set of one or more intensity thresholds to determine whether an operation has been performed by a user (e.g., to determine whether a user has “clicked” on an icon). In some embodiments, at least a subset of the intensity thresholds are determined in accordance with software parameters (e.g., the intensity thresholds are not determined by the activation thresholds of particular physical actuators and can be adjusted without changing the physical hardware of device 100). For example, a mouse “click” threshold of a trackpad or touch screen display can be set to any of a large range of predefined threshold values without changing the trackpad or touch screen display hardware. Additionally, in some implementations, a user of the device is provided with software settings for adjusting one or more of the set of intensity thresholds (e.g., by adjusting individual intensity thresholds and/or by adjusting a plurality of intensity thresholds at once with a system-level click “intensity” parameter).

Contact/motion module 130 optionally detects a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns (e.g., different motions, timings, and/or intensities of detected contacts). Thus, a gesture is, optionally, detected by detecting a particular contact pattern. For example, detecting a finger tap gesture includes detecting a finger-down event followed by detecting a finger-up (liftoff) event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up (liftoff) event.

Graphics module 132 includes various known software components for rendering and displaying graphics on touch screen 112 or other display, including components for changing the visual impact (e.g., brightness, transparency, saturation, contrast, or other visual property) of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user, including, without limitation, text, web pages, icons (such as user-interface objects including soft keys), digital images, videos, animations, and the like.

In some embodiments, graphics module 132 stores data representing graphics to be used. Each graphic is, optionally, assigned a corresponding code. Graphics module 132 receives, from applications etc., one or more codes specifying graphics to be displayed along with, if necessary, coordinate data and other graphic property data, and then generates screen image data to output to display controller 156.

Haptic feedback module 133 includes various software components for generating instructions used by tactile output generator(s) 167 to produce tactile outputs at one or more locations on device 100 in response to user interactions with device 100.

Text input module 134, which may be a component of graphics module 132, provides soft keyboards for entering text in various applications (e.g., contacts 137, e-mail 140, IM 141, browser 147, and any other application that needs text input).

GPS module 135 determines the location of the device and provides this information for use in various applications (e.g., to telephone 138 for use in location-based dialing; to camera 143 as picture/video metadata; and to applications that provide location-based services such as weather widgets, local yellow page widgets, and map/navigation widgets).

Applications 136 may include the following modules (or sets of instructions), or a subset or superset thereof:

Examples of other applications 136 that may be stored in memory 102 include other word processing applications, other image editing applications, drawing applications, presentation applications, JAVA-enabled applications, encryption, digital rights management, voice recognition, and voice replication.

In conjunction with touch screen 112, display controller 156, contact/motion module 130, graphics module 132, and text input module 134, contacts module 137 may be used to manage an address book or contact list (e.g., stored in application internal state 192 of contacts module 137 in memory 102 or memory 370), including: adding name(s) to the address book; deleting name(s) from the address book; associating telephone number(s), e-mail address(es), physical address(es) or other information with a name; associating an image with a name; categorizing and sorting names; providing telephone numbers or e-mail addresses to initiate and/or facilitate communications by telephone 138, video conference module 139, e-mail 140, or IM 141; and so forth.

In conjunction with RF circuitry 108, audio circuitry 110, speaker 111, microphone 113, touch screen 112, display controller 156, contact/motion module 130, graphics module 132, and text input module 134, telephone module 138 may be used to enter a sequence of characters corresponding to a telephone number, access one or more telephone numbers in contacts module 137, modify a telephone number that has been entered, dial a respective telephone number, conduct a conversation, and disconnect or hang up when the conversation is completed. As noted above, the wireless communication may use any of a plurality of communications standards, protocols, and technologies.

In conjunction with RF circuitry 108, audio circuitry 110, speaker 111, microphone 113, touch screen 112, display controller 156, optical sensor 164, optical sensor controller 158, contact/motion module 130, graphics module 132, text input module 134, contacts module 137, and telephone module 138, video conference module 139 includes executable instructions to initiate, conduct, and terminate a video conference between a user and one or more other participants in accordance with user instructions.

Additional description of the online video application can be found in U.S. Provisional Patent Application No. 60/936,562, “Portable Multifunction Device, Method, and Graphical User Interface for Playing Online Videos,” filed Jun. 20, 2007, and U.S. patent application Ser. No. 11/968,067, “Portable Multifunction Device, Method, and Graphical User Interface for Playing Online Videos,” filed Dec. 31, 2007, the contents of which are hereby incorporated by reference in their entirety.

Each of the above-identified modules and applications corresponds to a set of executable instructions for performing one or more functions described above and the methods described in this application (e.g., the computer-implemented methods and other information processing methods described herein). These modules (e.g., sets of instructions) need not be implemented as separate software programs, procedures, or modules, and thus various subsets of these modules may be combined or otherwise rearranged in various embodiments. For example, video player module may be combined with music player module into a single module (e.g., video and music player module 152, FIG. 1A). In some embodiments, memory 102 may store a subset of the modules and data structures identified above. Furthermore, memory 102 may store additional modules and data structures not described above.

In some embodiments, device 100 is a device where operation of a predefined set of functions on the device is performed exclusively through a touch screen and/or a touchpad. By using a touch screen and/or a touchpad as the primary input control device for operation of device 100, the number of physical input control devices (such as push buttons, dials, and the like) on device 100 may be reduced.

The predefined set of functions that are performed exclusively through a touch screen and/or a touchpad optionally include navigation between user interfaces. In some embodiments, the touchpad, when touched by the user, navigates device 100 to a main, home, or root menu from any user interface that is displayed on device 100. In such embodiments, a “menu button” is implemented using a touchpad. In some other embodiments, the menu button is a physical push button or other physical input control device instead of a touchpad.

FIG. 1B is a block diagram illustrating exemplary components for event handling in accordance with some embodiments. In some embodiments, memory 102 (FIG. 1A) or 370 (FIG. 3 ) includes event sorter 170 (e.g., in operating system 126) and a respective application 136-1 (e.g., any of the aforementioned applications 137-151, 155, 380-390).

Event sorter 170 receives event information and determines the application 136-1 and application view 191 of application 136-1 to which to deliver the event information. Event sorter 170 includes event monitor 171 and event dispatcher module 174. In some embodiments, application 136-1 includes application internal state 192, which indicates the current application view(s) displayed on touch-sensitive display 112 when the application is active or executing. In some embodiments, device/global internal state 157 is used by event sorter 170 to determine which application(s) is (are) currently active, and application internal state 192 is used by event sorter 170 to determine application views 191 to which to deliver event information.

In some embodiments, application internal state 192 includes additional information, such as one or more of: resume information to be used when application 136-1 resumes execution, user interface state information that indicates information being displayed or that is ready for display by application 136-1, a state queue for enabling the user to go back to a prior state or view of application 136-1, and a redo/undo queue of previous actions taken by the user.

Event monitor 171 receives event information from peripherals interface 118. Event information includes information about a sub-event (e.g., a user touch on touch-sensitive display 112, as part of a multi-touch gesture). Peripherals interface 118 transmits information it receives from I/O subsystem 106 or a sensor, such as proximity sensor 166, accelerometer(s) 168, and/or microphone 113 (through audio circuitry 110). Information that peripherals interface 118 receives from I/O subsystem 106 includes information from touch-sensitive display 112 or a touch-sensitive surface.

In some embodiments, event monitor 171 sends requests to the peripherals interface 118 at predetermined intervals. In response, peripherals interface 118 transmits event information. In other embodiments, peripherals interface 118 transmits event information only when there is a significant event (e.g., receiving an input above a predetermined noise threshold and/or for more than a predetermined duration).

In some embodiments, event sorter 170 also includes a hit view determination module 172 and/or an active event recognizer determination module 173.

Hit view determination module 172 provides software procedures for determining where a sub-event has taken place within one or more views when touch-sensitive display 112 displays more than one view. Views are made up of controls and other elements that a user can see on the display.

Another aspect of the user interface associated with an application is a set of views, sometimes herein called application views or user interface windows, in which information is displayed and touch-based gestures occur. The application views (of a respective application) in which a touch is detected may correspond to programmatic levels within a programmatic or view hierarchy of the application. For example, the lowest level view in which a touch is detected may be called the hit view, and the set of events that are recognized as proper inputs may be determined based, at least in part, on the hit view of the initial touch that begins a touch-based gesture.

Hit view determination module 172 receives information related to sub-events of a touch-based gesture. When an application has multiple views organized in a hierarchy, hit view determination module 172 identifies a hit view as the lowest view in the hierarchy which should handle the sub-event. In most circumstances, the hit view is the lowest level view in which an initiating sub-event occurs (e.g., the first sub-event in the sequence of sub-events that form an event or potential event). Once the hit view is identified by the hit view determination module 172, the hit view typically receives all sub-events related to the same touch or input source for which it was identified as the hit view.

Active event recognizer determination module 173 determines which view or views within a view hierarchy should receive a particular sequence of sub-events. In some embodiments, active event recognizer determination module 173 determines that only the hit view should receive a particular sequence of sub-events. In other embodiments, active event recognizer determination module 173 determines that all views that include the physical location of a sub-event are actively involved views, and therefore determines that all actively involved views should receive a particular sequence of sub-events. In other embodiments, even if touch sub-events were entirely confined to the area associated with one particular view, views higher in the hierarchy would still remain as actively involved views.

Event dispatcher module 174 dispatches the event information to an event recognizer (e.g., event recognizer 180). In embodiments including active event recognizer determination module 173, event dispatcher module 174 delivers the event information to an event recognizer determined by active event recognizer determination module 173. In some embodiments, event dispatcher module 174 stores in an event queue the event information, which is retrieved by a respective event receiver 182.

In some embodiments, operating system 126 includes event sorter 170. Alternatively, application 136-1 includes event sorter 170. In yet other embodiments, event sorter 170 is a stand-alone module, or a part of another module stored in memory 102, such as contact/motion module 130.

In some embodiments, application 136-1 includes a plurality of event handlers 190 and one or more application views 191, each of which includes instructions for handling touch events that occur within a respective view of the application's user interface. Each application view 191 of the application 136-1 includes one or more event recognizers 180. Typically, a respective application view 191 includes a plurality of event recognizers 180. In other embodiments, one or more of event recognizers 180 are part of a separate module, such as a user interface kit (not shown) or a higher level object from which application 136-1 inherits methods and other properties. In some embodiments, a respective event handler 190 includes one or more of: data updater 176, object updater 177, GUI updater 178, and/or event data 179 received from event sorter 170. Event handler 190 may utilize or call data updater 176, object updater 177, or GUI updater 178 to update the application internal state 192. Alternatively, one or more of the application views 191 include one or more respective event handlers 190. Also, in some embodiments, one or more of data updater 176, object updater 177, and GUI updater 178 are included in a respective application view 191.

A respective event recognizer 180 receives event information (e.g., event data 179) from event sorter 170 and identifies an event from the event information. Event recognizer 180 includes event receiver 182 and event comparator 184. In some embodiments, event recognizer 180 also includes at least a subset of: metadata 183, and event delivery instructions 188 (which may include sub-event delivery instructions).

Event receiver 182 receives event information from event sorter 170. The event information includes information about a sub-event, for example, a touch or a touch movement. Depending on the sub-event, the event information also includes additional information, such as location of the sub-event. When the sub-event concerns motion of a touch, the event information may also include speed and direction of the sub-event. In some embodiments, events include rotation of the device from one orientation to another (e.g., from a portrait orientation to a landscape orientation, or vice versa), and the event information includes corresponding information about the current orientation (also called device attitude) of the device.

Event comparator 184 compares the event information to predefined event or sub-event definitions and, based on the comparison, determines an event or sub-event, or determines or updates the state of an event or sub-event. In some embodiments, event comparator 184 includes event definitions 186. Event definitions 186 contain definitions of events (e.g., predefined sequences of sub-events), for example, event 1 (187-1), event 2 (187-2), and others. In some embodiments, sub-events in an event (187) include, for example, touch begin, touch end, touch movement, touch cancellation, and multiple touching. In one example, the definition for event 1 (187-1) is a double tap on a displayed object. The double tap, for example, comprises a first touch (touch begin) on the displayed object for a predetermined phase, a first liftoff (touch end) for a predetermined phase, a second touch (touch begin) on the displayed object for a predetermined phase, and a second liftoff (touch end) for a predetermined phase. In another example, the definition for event 2 (187-2) is a dragging on a displayed object. The dragging, for example, comprises a touch (or contact) on the displayed object for a predetermined phase, a movement of the touch across touch-sensitive display 112, and liftoff of the touch (touch end). In some embodiments, the event also includes information for one or more associated event handlers 190.

In some embodiments, event definition 187 includes a definition of an event for a respective user-interface object. In some embodiments, event comparator 184 performs a hit test to determine which user-interface object is associated with a sub-event. For example, in an application view in which three user-interface objects are displayed on touch-sensitive display 112, when a touch is detected on touch-sensitive display 112, event comparator 184 performs a hit test to determine which of the three user-interface objects is associated with the touch (sub-event). If each displayed object is associated with a respective event handler 190, the event comparator uses the result of the hit test to determine which event handler 190 should be activated. For example, event comparator 184 selects an event handler associated with the sub-event and the object triggering the hit test.

In some embodiments, the definition for a respective event (187) also includes delayed actions that delay delivery of the event information until after it has been determined whether the sequence of sub-events does or does not correspond to the event recognizer's event type.

When a respective event recognizer 180 determines that the series of sub-events do not match any of the events in event definitions 186, the respective event recognizer 180 enters an event impossible, event failed, or event ended state, after which it disregards subsequent sub-events of the touch-based gesture. In this situation, other event recognizers, if any, that remain active for the hit view continue to track and process sub-events of an ongoing touch-based gesture.

In some embodiments, a respective event recognizer 180 includes metadata 183 with configurable properties, flags, and/or lists that indicate how the event delivery system should perform sub-event delivery to actively involved event recognizers. In some embodiments, metadata 183 includes configurable properties, flags, and/or lists that indicate how event recognizers may interact, or are enabled to interact, with one another. In some embodiments, metadata 183 includes configurable properties, flags, and/or lists that indicate whether sub-events are delivered to varying levels in the view or programmatic hierarchy.

In some embodiments, a respective event recognizer 180 activates event handler 190 associated with an event when one or more particular sub-events of an event are recognized. In some embodiments, a respective event recognizer 180 delivers event information associated with the event to event handler 190. Activating an event handler 190 is distinct from sending (and deferred sending) sub-events to a respective hit view. In some embodiments, event recognizer 180 throws a flag associated with the recognized event, and event handler 190 associated with the flag catches the flag and performs a predefined process.

In some embodiments, event delivery instructions 188 include sub-event delivery instructions that deliver event information about a sub-event without activating an event handler. Instead, the sub-event delivery instructions deliver event information to event handlers associated with the series of sub-events or to actively involved views. Event handlers associated with the series of sub-events or with actively involved views receive the event information and perform a predetermined process.

In some embodiments, data updater 176 creates and updates data used in application 136-1. For example, data updater 176 updates the telephone number used in contacts module 137, or stores a video file used in video player module. In some embodiments, object updater 177 creates and updates objects used in application 136-1. For example, object updater 177 creates a new user-interface object or updates the position of a user-interface object. GUI updater 178 updates the GUI. For example, GUI updater 178 prepares display information and sends it to graphics module 132 for display on a touch-sensitive display.

In some embodiments, event handler(s) 190 includes or has access to data updater 176, object updater 177, and GUI updater 178. In some embodiments, data updater 176, object updater 177, and GUI updater 178 are included in a single module of a respective application 136-1 or application view 191. In other embodiments, they are included in two or more software modules.

It shall be understood that the foregoing discussion regarding event handling of user touches on touch-sensitive displays also applies to other forms of user inputs to operate multifunction devices 100 with input devices, not all of which are initiated on touch screens. For example, mouse movement and mouse button presses, optionally coordinated with single or multiple keyboard presses or holds; contact movements such as taps, drags, scrolls, etc. on touchpads; pen stylus inputs; movement of the device; oral instructions; detected eye movements; biometric inputs; and/or any combination thereof are optionally utilized as inputs corresponding to sub-events which define an event to be recognized.

FIG. 2 illustrates a portable multifunction device 100 having a touch screen 112 in accordance with some embodiments. The touch screen optionally displays one or more graphics within user interface (UI) 200. In this embodiment, as well as others described below, a user is enabled to select one or more of the graphics by making a gesture on the graphics, for example, with one or more fingers 202 (not drawn to scale in the figure) or one or more styluses 203 (not drawn to scale in the figure). In some embodiments, selection of one or more graphics occurs when the user breaks contact with the one or more graphics. In some embodiments, the gesture optionally includes one or more taps, one or more swipes (from left to right, right to left, upward and/or downward), and/or a rolling of a finger (from right to left, left to right, upward and/or downward) that has made contact with device 100. In some implementations or circumstances, inadvertent contact with a graphic does not select the graphic. For example, a swipe gesture that sweeps over an application icon optionally does not select the corresponding application when the gesture corresponding to selection is a tap.

Device 100 may also include one or more physical buttons, such as “home” or menu button 204. As described previously, menu button 204 may be used to navigate to any application 136 in a set of applications that may be executed on device 100. Alternatively, in some embodiments, the menu button is implemented as a soft key in a GUI displayed on touch screen 112.

In one embodiment, device 100 includes touch screen 112, menu button 204, push button 206 for powering the device on/off and locking the device, volume adjustment button(s) 208, subscriber identity module (SIM) card slot 210, headset jack 212, and docking/charging external port 124. Push button 206 is, optionally, used to turn the power on/off on the device by depressing the button and holding the button in the depressed state for a predefined time interval; to lock the device by depressing the button and releasing the button before the predefined time interval has elapsed; and/or to unlock the device or initiate an unlock process. In an alternative embodiment, device 100 also accepts verbal input for activation or deactivation of some functions through microphone 113. Device 100 also, optionally, includes one or more contact intensity sensors 165 for detecting intensity of contacts on touch screen 112 and/or one or more tactile output generators 167 for generating tactile outputs for a user of device 100.

FIG. 3 is a block diagram of an exemplary multifunction device with a display and a touch-sensitive surface in accordance with some embodiments. Device 300 need not be portable. In some embodiments, device 300 is a laptop computer, a desktop computer, a tablet computer, a multimedia player device, a navigation device, an educational device (such as a child's learning toy), a gaming system, or a control device (e.g., a home or industrial controller). Device 300 typically includes one or more processing units (CPUs) 310, one or more network or other communications interfaces 360, memory 370, and one or more communication buses 320 for interconnecting these components. Communication buses 320 optionally include circuitry (sometimes called a chipset) that interconnects and controls communications between system components. Device 300 includes input/output (I/O) interface 330 comprising display 340, which is typically a touch screen display. I/O interface 330 also optionally includes a keyboard and/or mouse (or other pointing device) 350 and touchpad 355, tactile output generator 357 for generating tactile outputs on device 300 (e.g., similar to tactile output generator(s) 167 described above with reference to FIG. 1A), sensors 359 (e.g., optical, acceleration, proximity, touch-sensitive, and/or contact intensity sensors similar to contact intensity sensor(s) 165 described above with reference to FIG. 1A). Memory 370 includes high-speed random access memory, such as DRAM, SRAM, DDR RAM, or other random access solid state memory devices; and optionally includes non-volatile memory, such as one or more magnetic disk storage devices, optical disk storage devices, flash memory devices, or other non-volatile solid state storage devices. Memory 370 optionally includes one or more storage devices remotely located from CPU(s) 310. In some embodiments, memory 370 stores programs, modules, and data structures analogous to the programs, modules, and data structures stored in memory 102 of portable multifunction device 100 (FIG. 1A), or a subset thereof. Furthermore, memory 370 optionally stores additional programs, modules, and data structures not present in memory 102 of portable multifunction device 100. For example, memory 370 of device 300 optionally stores drawing module 380, presentation module 382, word processing module 384, website creation module 386, disk authoring module 388, and/or spreadsheet module 390, while memory 102 of portable multifunction device 100 (FIG. 1A) optionally does not store these modules.

Each of the above-identified elements in FIG. 3 may be stored in one or more of the previously mentioned memory devices. Each of the above-identified modules corresponds to a set of instructions for performing a function described above. The above-identified modules or programs (e.g., sets of instructions) need not be implemented as separate software programs, procedures, or modules, and thus various subsets of these modules may be combined or otherwise rearranged in various embodiments. In some embodiments, memory 370 may store a subset of the modules and data structures identified above. Furthermore, memory 370 may store additional modules and data structures not described above.

Attention is now directed towards embodiments of user interfaces that may be implemented on, for example, portable multifunction device 100.

FIG. 4A illustrates an exemplary user interface for a menu of applications on portable multifunction device 100 in accordance with some embodiments. Similar user interfaces may be implemented on device 300. In some embodiments, user interface 400 includes the following elements, or a subset or superset thereof:

-   -   Signal strength indicator(s) 402 for wireless communication(s),         such as cellular and Wi-Fi signals;     -   Time 404;     -   Bluetooth indicator 405;     -   Battery status indicator 406;     -   Tray 408 with icons for frequently used applications, such as:         -   Icon 416 for telephone module 138, labeled “Phone,” which             optionally includes an indicator 414 of the number of missed             calls or voicemail messages;         -   Icon 418 for e-mail client module 140, labeled “Mail,” which             optionally includes an indicator 410 of the number of unread             e-mails;         -   Icon 420 for browser module 147, labeled “Browser;” and         -   Icon 422 for video and music player module 152, also             referred to as iPod (trademark of Apple Inc.) module 152,             labeled “iPod;” and     -   Icons for other applications, such as:         -   Icon 424 for IM module 141, labeled “Messages;”         -   Icon 426 for calendar module 148, labeled “Calendar;”         -   Icon 428 for image management module 144, labeled “Photos;”         -   Icon 430 for camera module 143, labeled “Camera;”         -   Icon 432 for online video module 155, labeled “Online             Video;”         -   Icon 434 for stocks widget 149-2, labeled “Stocks;”         -   Icon 436 for map module 154, labeled “Maps;”         -   Icon 438 for weather widget 149-1, labeled “Weather;”         -   Icon 440 for alarm clock widget 149-4, labeled “Clock;”         -   Icon 442 for workout support module 142, labeled “Workout             Support;”         -   Icon 444 for notes module 153, labeled “Notes;” and         -   Icon 446 for a settings application or module, labeled             “Settings,” which provides access to settings for device 100             and its various applications 136.

It should be noted that the icon labels illustrated in FIG. 4A are merely exemplary. For example, icon 422 for video and music player module 152 may optionally be labeled “Music” or “Music Player.” Other labels are, optionally, used for various application icons. In some embodiments, a label for a respective application icon includes a name of an application corresponding to the respective application icon. In some embodiments, a label for a particular application icon is distinct from a name of an application corresponding to the particular application icon.

FIG. 4B illustrates an exemplary user interface on a device (e.g., device 300, FIG. 3 ) with a touch-sensitive surface 451 (e.g., a tablet or touchpad 355, FIG. 3 ) that is separate from the display 450 (e.g., touch screen display 112). Device 300 also, optionally, includes one or more contact intensity sensors (e.g., one or more of sensors 357) for detecting intensity of contacts on touch-sensitive surface 451 and/or one or more tactile output generators 359 for generating tactile outputs for a user of device 300.

Although some of the examples which follow will be given with reference to inputs on touch screen display 112 (where the touch-sensitive surface and the display are combined), in some embodiments, the device detects inputs on a touch-sensitive surface that is separate from the display, as shown in FIG. 4B. In some embodiments, the touch-sensitive surface (e.g., 451 in FIG. 4B) has a primary axis (e.g., 452 in FIG. 4B) that corresponds to a primary axis (e.g., 453 in FIG. 4B) on the display (e.g., 450). In accordance with these embodiments, the device detects contacts (e.g., 460 and 462 in FIG. 4B) with the touch-sensitive surface 451 at locations that correspond to respective locations on the display (e.g., in FIG. 4B, 460 corresponds to 468 and 462 corresponds to 470). In this way, user inputs (e.g., contacts 460 and 462, and movements thereof) detected by the device on the touch-sensitive surface (e.g., 451 in FIG. 4B) are used by the device to manipulate the user interface on the display (e.g., 450 in FIG. 4B) of the multifunction device when the touch-sensitive surface is separate from the display. It should be understood that similar methods are, optionally, used for other user interfaces described herein.

Additionally, while the following examples are given primarily with reference to finger inputs (e.g., finger contacts, finger tap gestures, finger swipe gestures), it should be understood that, in some embodiments, one or more of the finger inputs are replaced with input from another input device (e.g., a mouse-based input or stylus input). For example, a swipe gesture is, optionally, replaced with a mouse click (e.g., instead of a contact) followed by movement of the cursor along the path of the swipe (e.g., instead of movement of the contact). As another example, a tap gesture is, optionally, replaced with a mouse click while the cursor is located over the location of the tap gesture (e.g., instead of detection of the contact followed by ceasing to detect the contact). Similarly, when multiple user inputs are simultaneously detected, it should be understood that multiple computer mice are, optionally, used simultaneously, or a mouse and finger contacts are, optionally, used simultaneously.

FIG. 5A illustrates exemplary personal electronic device 500. Device 500 includes body 502. In some embodiments, device 500 can include some or all of the features described with respect to devices 100 and 300 (e.g., FIGS. 1A-4B). In some embodiments, device 500 has touch-sensitive display screen 504, hereafter touch screen 504. Alternatively, or in addition to touch screen 504, device 500 has a display and a touch-sensitive surface. As with devices 100 and 300, in some embodiments, touch screen 504 (or the touch-sensitive surface) may have one or more intensity sensors for detecting intensity of contacts (e.g., touches) being applied. The one or more intensity sensors of touch screen 504 (or the touch-sensitive surface) can provide output data that represents the intensity of touches. The user interface of device 500 can respond to touches based on their intensity, meaning that touches of different intensities can invoke different user interface operations on device 500.

Techniques for detecting and processing touch intensity may be found, for example, in related applications: International Patent Application Serial No. PCT/US2013/040061, titled “Device, Method, and Graphical User Interface for Displaying User Interface Objects Corresponding to an Application,” filed May 8, 2013, and International Patent Application Serial No. PCT/US2013/069483, titled “Device, Method, and Graphical User Interface for Transitioning Between Touch Input to Display Output Relationships,” filed Nov. 11, 2013, each of which is hereby incorporated by reference in their entirety.

In some embodiments, device 500 has one or more input mechanisms 506 and 508.

Input mechanisms 506 and 508, if included, can be physical. Examples of physical input mechanisms include push buttons and rotatable mechanisms. In some embodiments, device 500 has one or more attachment mechanisms. Such attachment mechanisms, if included, can permit attachment of device 500 with, for example, hats, eyewear, earrings, necklaces, shirts, jackets, bracelets, watch straps, chains, trousers, belts, shoes, purses, backpacks, and so forth. These attachment mechanisms may permit device 500 to be worn by a user.

FIG. 5B depicts exemplary personal electronic device 500. In some embodiments, device 500 can include some or all of the components described with respect to FIGS. 1A, 1B, and 3. Device 500 has bus 512 that operatively couples I/O section 514 with one or more computer processors 516 and memory 518. I/O section 514 can be connected to display 504, which can have touch-sensitive component 522 and, optionally, touch-intensity sensitive component 524. In addition, I/O section 514 can be connected with communication unit 530 for receiving application and operating system data, using Wi-Fi, Bluetooth, near field communication (NFC), cellular, and/or other wireless communication techniques. Device 500 can include input mechanisms 506 and/or 508. Input mechanism 506 may be a rotatable input device or a depressible and rotatable input device, for example. Input mechanism 508 may be a button, in some examples.

Input mechanism 508 may be a microphone, in some examples. Personal electronic device 500 can include various sensors, such as GPS sensor 532, accelerometer 534, directional sensor 540 (e.g., compass), gyroscope 536, motion sensor 538, and/or a combination thereof, all of which can be operatively connected to I/O section 514.

Memory 518 of personal electronic device 500 can be a non-transitory computer-readable storage medium, for storing computer-executable instructions, which, when executed by one or more computer processors 516, for example, can cause the computer processors to perform the techniques described above, including processes 1300-2000 (FIGS. 13-20 ). The computer-executable instructions can also be stored and/or transported within any non-transitory computer-readable storage medium for use by or in connection with an instruction execution system, apparatus, or device, such as a computer-based system, processor-containing system, or other system that can fetch the instructions from the instruction execution system, apparatus, or device and execute the instructions. For purposes of this document, a “non-transitory computer-readable storage medium” can be any medium that can tangibly contain or store computer-executable instructions for use by or in connection with the instruction execution system, apparatus, or device. The non-transitory computer-readable storage medium can include, but is not limited to, magnetic, optical, and/or semiconductor storages. Examples of such storage include magnetic disks, optical discs based on CD, DVD, or Blu-ray technologies, as well as persistent solid-state memory such as flash, solid-state drives, and the like. Personal electronic device 500 is not limited to the components and configuration of FIG. 5B, but can include other or additional components in multiple configurations.

As used here, the term “affordance” refers to a user-interactive graphical user interface object that may be displayed on the display screen of devices 100, 300, and/or 500 (FIGS. 1, 3, and 5 ). For example, an image (e.g., icon), a button, and text (e.g., hyperlink) may each constitute an affordance.

As used herein, the term “focus selector” refers to an input element that indicates a current part of a user interface with which a user is interacting. In some implementations that include a cursor or other location marker, the cursor acts as a “focus selector” so that when an input (e.g., a press input) is detected on a touch-sensitive surface (e.g., touchpad 355 in FIG. 3 or touch-sensitive surface 451 in FIG. 4B) while the cursor is over a particular user interface element (e.g., a button, window, slider or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations that include a touch screen display (e.g., touch-sensitive display system 112 in FIG. 1A or touch screen 112 in FIG. 4A) that enables direct interaction with user interface elements on the touch screen display, a detected contact on the touch screen acts as a “focus selector” so that when an input (e.g., a press input by the contact) is detected on the touch screen display at a location of a particular user interface element (e.g., a button, window, slider, or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations, focus is moved from one region of a user interface to another region of the user interface without corresponding movement of a cursor or movement of a contact on a touch screen display (e.g., by using a tab key or arrow keys to move focus from one button to another button); in these implementations, the focus selector moves in accordance with movement of focus between different regions of the user interface. Without regard to the specific form taken by the focus selector, the focus selector is generally the user interface element (or contact on a touch screen display) that is controlled by the user so as to communicate the user's intended interaction with the user interface (e.g., by indicating, to the device, the element of the user interface with which the user is intending to interact). For example, the location of a focus selector (e.g., a cursor, a contact, or a selection box) over a respective button while a press input is detected on the touch-sensitive surface (e.g., a touchpad or touch screen) will indicate that the user is intending to activate the respective button (as opposed to other user interface elements shown on a display of the device).

As used in the specification and claims, the term “characteristic intensity” of a contact refers to a characteristic of the contact based on one or more intensities of the contact. In some embodiments, the characteristic intensity is based on multiple intensity samples. The characteristic intensity is, optionally, based on a predefined number of intensity samples, or a set of intensity samples collected during a predetermined time period (e.g., 0.05, 0.1, 0.2, 0.5, 1, 2, 5, 10 seconds) relative to a predefined event (e.g., after detecting the contact, prior to detecting liftoff of the contact, before or after detecting a start of movement of the contact, prior to detecting an end of the contact, before or after detecting an increase in intensity of the contact, and/or before or after detecting a decrease in intensity of the contact). A characteristic intensity of a contact is, optionally based on one or more of: a maximum value of the intensities of the contact, a mean value of the intensities of the contact, an average value of the intensities of the contact, a top 10 percentile value of the intensities of the contact, a value at the half maximum of the intensities of the contact, a value at the 90 percent maximum of the intensities of the contact, or the like. In some embodiments, the duration of the contact is used in determining the characteristic intensity (e.g., when the characteristic intensity is an average of the intensity of the contact over time). In some embodiments, the characteristic intensity is compared to a set of one or more intensity thresholds to determine whether an operation has been performed by a user. For example, the set of one or more intensity thresholds may include a first intensity threshold and a second intensity threshold. In this example, a contact with a characteristic intensity that does not exceed the first threshold results in a first operation, a contact with a characteristic intensity that exceeds the first intensity threshold and does not exceed the second intensity threshold results in a second operation, and a contact with a characteristic intensity that exceeds the second threshold results in a third operation. In some embodiments, a comparison between the characteristic intensity and one or more thresholds is used to determine whether or not to perform one or more operations (e.g., whether to perform a respective operation or forgo performing the respective operation) rather than being used to determine whether to perform a first operation or a second operation.

In some embodiments, a portion of a gesture is identified for purposes of determining a characteristic intensity. For example, a touch-sensitive surface may receive a continuous swipe contact transitioning from a start location and reaching an end location, at which point the intensity of the contact increases. In this example, the characteristic intensity of the contact at the end location may be based on only a portion of the continuous swipe contact, and not the entire swipe contact (e.g., only the portion of the swipe contact at the end location). In some embodiments, a smoothing algorithm may be applied to the intensities of the swipe contact prior to determining the characteristic intensity of the contact. For example, the smoothing algorithm optionally includes one or more of: an unweighted sliding-average smoothing algorithm, a triangular smoothing algorithm, a median filter smoothing algorithm, and/or an exponential smoothing algorithm. In some circumstances, these smoothing algorithms eliminate narrow spikes or dips in the intensities of the swipe contact for purposes of determining a characteristic intensity.

The intensity of a contact on the touch-sensitive surface may be characterized relative to one or more intensity thresholds, such as a contact-detection intensity threshold, a light press intensity threshold, a deep press intensity threshold, and/or one or more other intensity thresholds. In some embodiments, the light press intensity threshold corresponds to an intensity at which the device will perform operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, the deep press intensity threshold corresponds to an intensity at which the device will perform operations that are different from operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, when a contact is detected with a characteristic intensity below the light press intensity threshold (e.g., and above a nominal contact-detection intensity threshold below which the contact is no longer detected), the device will move a focus selector in accordance with movement of the contact on the touch-sensitive surface without performing an operation associated with the light press intensity threshold or the deep press intensity threshold. Generally, unless otherwise stated, these intensity thresholds are consistent between different sets of user interface figures.

An increase of characteristic intensity of the contact from an intensity below the light press intensity threshold to an intensity between the light press intensity threshold and the deep press intensity threshold is sometimes referred to as a “light press” input. An increase of characteristic intensity of the contact from an intensity below the deep press intensity threshold to an intensity above the deep press intensity threshold is sometimes referred to as a “deep press” input. An increase of characteristic intensity of the contact from an intensity below the contact-detection intensity threshold to an intensity between the contact-detection intensity threshold and the light press intensity threshold is sometimes referred to as detecting the contact on the touch-surface. A decrease of characteristic intensity of the contact from an intensity above the contact-detection intensity threshold to an intensity below the contact-detection intensity threshold is sometimes referred to as detecting liftoff of the contact from the touch-surface. In some embodiments, the contact-detection intensity threshold is zero. In some embodiments, the contact-detection intensity threshold is greater than zero.

In some embodiments described herein, one or more operations are performed in response to detecting a gesture that includes a respective press input or in response to detecting the respective press input performed with a respective contact (or a plurality of contacts), where the respective press input is detected based at least in part on detecting an increase in intensity of the contact (or plurality of contacts) above a press-input intensity threshold. In some embodiments, the respective operation is performed in response to detecting the increase in intensity of the respective contact above the press-input intensity threshold (e.g., a “down stroke” of the respective press input). In some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the press-input threshold (e.g., an “up stroke” of the respective press input).

In some embodiments, the device employs intensity hysteresis to avoid accidental inputs sometimes termed “jitter,” where the device defines or selects a hysteresis intensity threshold with a predefined relationship to the press-input intensity threshold (e.g., the hysteresis intensity threshold is X intensity units lower than the press-input intensity threshold or the hysteresis intensity threshold is 75%, 90%, or some reasonable proportion of the press-input intensity threshold). Thus, in some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the hysteresis intensity threshold that corresponds to the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the hysteresis intensity threshold (e.g., an “up stroke” of the respective press input). Similarly, in some embodiments, the press input is detected only when the device detects an increase in intensity of the contact from an intensity at or below the hysteresis intensity threshold to an intensity at or above the press-input intensity threshold and, optionally, a subsequent decrease in intensity of the contact to an intensity at or below the hysteresis intensity, and the respective operation is performed in response to detecting the press input (e.g., the increase in intensity of the contact or the decrease in intensity of the contact, depending on the circumstances).

For ease of explanation, the descriptions of operations performed in response to a press input associated with a press-input intensity threshold or in response to a gesture including the press input are, optionally, triggered in response to detecting either: an increase in intensity of a contact above the press-input intensity threshold, an increase in intensity of a contact from an intensity below the hysteresis intensity threshold to an intensity above the press-input intensity threshold, a decrease in intensity of the contact below the press-input intensity threshold, and/or a decrease in intensity of the contact below the hysteresis intensity threshold corresponding to the press-input intensity threshold. Additionally, in examples where an operation is described as being performed in response to detecting a decrease in intensity of a contact below the press-input intensity threshold, the operation is, optionally, performed in response to detecting a decrease in intensity of the contact below a hysteresis intensity threshold corresponding to, and lower than, the press-input intensity threshold.

FIG. 6A shows exemplary button functionalities for user interfaces that may be operated on device 600. Device 600 may be device 100, 300, or 500 in some embodiments. The electronic device has a display (e.g., 504). As shown in FIG. 6A, device 600 includes rotatable and depressible input mechanism 602. A rotatable and depressible input mechanism adds functionality to device 600 by providing multiple modes of user activation, thereby increasing user interactivity and/or ease of use with any of the user interfaces operable on device 600. The electronic device may also include a touch-sensitive surface (e.g., 504) and a button (e.g., 508).

A user may activate rotatable and depressible input mechanism 602 by activation 604. Depicted activation arrow blocks (e.g., activation 604) are typically not part of the displayed user interface, but are provided to aid in the interpretation of the figures. As depicted in FIG. 6A by the arrow block, activation 604 has an associated activation duration (e.g., a duration of time during which the activation is continuously detected by the device). In response to receiving data representing the activation, the device determines whether the activation duration exceeds a predetermined threshold. In some embodiments, the predetermined threshold is a predetermined length of time. In response to receiving data representing the activation, the device also determines a state of an active application. An active application may include a current application, a home screen of the device, a clock face displayed on the device, and so forth. For example, a state of a current application could be a state of an application with which the user is currently interacting. Alternatively, a state of an active application could refer to a currently displayed screen on the device, such as a clock face or a home screen.

In accordance with a determination that the activation duration exceeds the predetermined threshold (e.g., the input is an extended press of rotatable and depressible input mechanism 602, as depicted by the long arrow block shown for activation 604), and in accordance with a determination of the state of the active application, the device performs an action. In some embodiments, the action may be related or otherwise corresponding to the state of the active application. For example, the device may perform an action that is related to the currently displayed content or user interface of the device. In this way, the rotatable and depressible input mechanism may provide different functionalities depending on how the user is interacting with the device (e.g., a displayed user interface).

In some embodiments, a rotatable and depressible input mechanism (e.g., 602) is a mechanical button that is rotatable, and the activation is a physical depression of the mechanical button. In some embodiments, a rotatable and depressible input mechanism (e.g., 602) is a capacitive button that is rotatable, and the activation is a touch on the capacitive button. In either case, the rotatable and depressible input mechanism retains two modes of user interaction, which advantageously may be used for different purposes. In some embodiments, the activation (e.g., 604) does not represent a rotation of the rotatable and depressible input mechanism. In some embodiments, detection of the activation is based on detecting a press such as a physical depression or a touch and does not require a rotation for detection. For example, the device may perform an action in response to an activation of rotatable and depressible input mechanism 602, and it may scroll or cycle through content or options based on the action in response to a rotation.

In some embodiments, in accordance with a determination that the state of the active application relates to user-to-user voice communication, the device may invoke an application for low-latency asynchronous voice communication (e.g., a walkie talkie-type function). For example, if the active application provides a voice communication interface, an extended press of the rotatable and depressible input mechanism could activate a low-latency asynchronous voice communication functionality.

In some embodiments, after invoking the application for low-latency asynchronous voice communication, the device receives a voice input and transmits the voice input to a second electronic device capable of receiving the voice input. As an illustrative example, in the low-latency asynchronous voice communication application, a user may speak while activating the rotatable and depressible input mechanism for an extended press, listen to a response from the second device while the rotatable and depressible input mechanism is not being activated, then speak again while activating the rotatable and depressible input mechanism for an extended press.

In some embodiments, in accordance with a determination that the state of the active application relates to transcribing a voice input, the device may invoke a dictation application, receive a voice input, and transcribe the voice input into a displayed text. For example, if the user is in a state of an application that receives text input (e.g., from a physical or virtual keyboard, such as a notes application), an extended press on the rotatable and depressible input mechanism may invoke a dictation application to receive instead a speech input from the user, which can be transcribed by the device into displayed text. As shown in FIG. 6A, device 600 has received a voice input and shows displayed text 606, which was transcribed from the voice input.

In some embodiments, in accordance with a determination that the state of the active application relates to audio messaging, the device may invoke an audio messaging application, record a voice input, and send data representing the recorded voice input to a second electronic device capable of receiving the data. For example, if the user is in a text messaging application, an extended press on the rotatable and depressible input mechanism may invoke an audio messaging application to send an audio file to a recipient (e.g., a participant in a text messaging conversation).

In some embodiments, in accordance with a determination that the state of the active application relates to receiving a voice request to execute a task, or in accordance with a determination that the state of the current application does not relate to user-to-user voice communication or transcribing a voice input, the device may invoke a virtual assistant. Further description of a virtual assistant may be found, for example, in related application U.S. Utility application Ser. No. 12/987,982, entitled “Intelligent Automated Assistant,” filed Jan. 10, 2011 application.

For example, if the user is in a state of an application for executing a task, the device may invoke the virtual assistant to execute the task. Alternatively, invoking a virtual assistant may represent a default, such that the device may invoke a virtual assistant upon receiving an extended press of the rotatable and depressible input mechanism while the user is in any state of any application not explicitly assigned to invoke a different function. As described above, the functionalities invoked by an extended press of the rotatable and depressible input mechanism all relate to a speech or voice input. This unites the functions invokable through an extended press of the rotatable and depressible input mechanism by a common general feature, which helps the comprehensibility and intuitiveness of the device. Further, this allows for invoking multiple features through the same user input by determining which feature to invoke dependent upon a state of an active application. A user may be more likely to want to invoke a particular function if the user is in a state of an active application that is related to the function.

In some embodiments, after invoking the virtual assistant, the device displays a user interface screen on the display. This user interface screen includes a user prompt for voice input. A user prompt for voice input may include a text prompting the user to enter a voice input or an affordance representing a voice input (such as a microphone, speech balloon, or other depiction related to a voice input). As used here, the term “affordance” refers to a user-interactive graphical user interface object that may be displayed on the display screen of device 100, 300, and/or 500 (FIGS. 1, 3, and 5A). For example, an image (e.g., icon), a virtual button, and text may each constitute an affordance. In some embodiments, the device may further receive a voice input.

In some embodiments, after receiving the voice input, the device transcribes the voice input into text and displays the text on the display. For example, in FIG. 6A, device 600 has transcribed a voice input from the user and displayed transcribed text (e.g., 606) based on the voice input on the display. In some embodiments, the device also displays a waveform based on the voice input on the display (e.g., waveform 608). A waveform based on a voice input may graphically represent a sound wave, but it need not depict a sound wave that is precisely based on the physical characteristics of the voice input (e.g., the waveform may not be a mathematical representation of the actual sound wave of the voice input). In some embodiments, the waveform is a stylized representation of a sound wave sufficient to connote to the user that the voice input is received by the device. In some embodiments, one or more characteristics of the waveform is based on a physical characteristic of the voice input (e.g., frequency, amplitude, wave length, and so forth).

In some embodiments, the device displays the waveform on the display at a position adjacent to the rotatable and depressible input mechanism (e.g., a portion of the waveform is at a position proximal to the rotatable and depressible input mechanism). As shown in FIG. 6A, waveform 608 is displayed by device 600 at a position next to rotatable and depressible input mechanism 602. Advantageously, this helps the user recognize that activation of the rotatable and depressible input mechanism invokes an application for receiving a voice input depicted by the waveform, thereby increasing the usability and intuitive feel of the interface through the rotatable and depressible input mechanism functionality.

In some embodiments, the device determines whether the voice input contains a request to execute a task executable by the virtual assistant, and in accordance with a determination that the voice input contains a request to execute a task executable by the virtual assistant, the device executes the task by the virtual assistant. Further details on this determination and tasks executed by a virtual assistant may be found in the related application cited above.

An embodiment of these concepts is illustrated in FIG. 6B. FIG. 6B shows device 600 receiving a voice input with a request to text Adrian “Do you have time for coffee.” Device 600 has transcribed this voice request into displayed texts 614 and 624 on user interface screens 610 and 620, respectively. Waveform 612 is displayed on user interface screen 610 next to rotatable and depressible input mechanism 616. As illustrated by the transition from user interface screen 610 to user interface screen 620, waveform 612 is animated to appear as if emanating from rotatable and depressible input mechanism 616, as it progresses fully across the display as waveform 622 on user interface screen 620, which is positioned next to rotatable and depressible input mechanism 626. Similar to what was described above, this animation further strengthens the user's connection between the rotatable and depressible input mechanism itself and its functionality.

In some embodiments, the virtual assistant is run on the electronic device. In some embodiments, the virtual assistant is run on an external device in wireless communication with the electronic device. As used herein, invoking a virtual assistant, determining whether a voice input contains a request to execute a task executable by the virtual assistant, and/or executing a task using a virtual assistant may be performed on or by the device itself or by wirelessly communicating with one or more external devices, such as an electronic device (e.g., a phone, laptop, desktop, or tablet computer), server, and the like. For example, the device may execute a task on an external device or by using data from an external device. One or more of the functions required to execute the task (e.g., receiving a voice input, determining whether the voice input contains a request to execute a task, determining whether the task is executable by the virtual assistant, and executing the task) may be performed on an external device in wireless communication with the device (e.g., device 600) using data from the device and/or by sending data to the device.

In some embodiments, the device may send first data representing the voice input to an external device, receive from the external device second data representing a request to execute a task executable by the virtual assistant, transcribe the request into text, and display the text on the display (e.g., text 608, 614, or 624). The device may receive the second data via wireless communication (e.g., Wi-Fi, Bluetooth™, near field communication (“NFC”), cellular and/or other wireless communication techniques, and so forth).

In some embodiments, the device displays an affordance representing a user prompt to display additional data related to the request on an external device. That is to say, the device may indicate to the user that additional data may be viewed on the external device, which may be particularly advantageous if the electronic device has a display smaller than the display of the external device. Additional data related to the request may include further or more detailed data requested by the user. For example, if the request is for weather information, the device may display weather information such as a predicted or current weather condition, temperature, and the like, and the user may view more detailed weather information (such as moon phase, humidity, barometric pressure, a weekly forecast, and so forth) on the external device.

In some embodiments, a rotatable and depressible input mechanism may include any of the functionalities described above in combination with one or more of the other functionalities described herein for a rotatable and depressible input mechanism. In some embodiments, device 600 may also include a button (e.g., 508) with one or more of the functionalities described herein for a button.

FIG. 7 shows exemplary button functionalities for user interfaces that may be operated on device 700. Device 700 may be device 100, 300, or 500 in some embodiments. The electronic device has a display (e.g., 504). As shown in FIG. 7 , device 700 includes rotatable and depressible input mechanism 702. The electronic device may also include a touch-sensitive surface (e.g., 504) and a button (e.g., 508).

A user may activate rotatable and depressible input mechanism 702 by activation 704. As depicted in FIG. 7 by the arrow block, activation 704 has an associated activation duration. In response to receiving data representing the activation, the device determines whether the activation duration exceeds a predetermined threshold. In some embodiments, the predetermined threshold is a predetermined length of time.

In accordance with a determination that the activation duration does not exceed the predetermined threshold (e.g., the input is a single press of rotatable and depressible input mechanism 702, as depicted by the short, single arrow block shown for activation 704), the device displays a first user interface screen including a plurality of affordances on the display. For example, device 700 displays user interface screen 706 that includes a plurality of affordances that includes affordances 708 and 710. In the plurality, at least a first affordance represents an application. For example, the affordance may be an affordance such as an icon that, when activated, causes the application to be displayed (e.g., affordances may include user-interactive icons for launching a software application). An affordance representing an application may convey to the user the application through texts, symbols, icons, depictions of an application-related screen, or any other visual indication that represents the application. In some embodiments, user interface screen 706 may be a home screen that includes a plurality of affordances representing applications.

While the first user interface screen is displayed, a user may activate rotatable and depressible input mechanism 702 with a second activation having a second activation duration. In response to receiving the data, the device determines whether the second activation duration exceeds a second predetermined threshold. In accordance with a determination that the second activation duration does not exceed the second predetermined threshold (e.g., the input is a single press of the rotatable and depressible input mechanism), the device displays a second user interface screen (e.g., 720) that includes a clock face (e.g., 722). In some embodiments, the order of screens may be reversed, such that a first single press causes the display of a clock face (e.g., 722), and a second single press causes the display of a plurality of application affordances (e.g, 708 and 710). Linking these functions allows the user to easily navigate between a clock face and application affordances, which is advantageous if the user uses the device to keep time and to use applications.

In some embodiments, the device displays a user interface screen that includes a clock face. While the user interface screen is displayed, a user may activate rotatable and depressible input mechanism 702 with a third activation having a third activation duration. In response to receiving the data, the device determines whether the third activation duration exceeds a third predetermined threshold. In accordance with a determination that the third activation duration does not exceed the third predetermined threshold (e.g., the input is a single press of the rotatable and depressible input mechanism), the device displays a second user interface screen that includes a plurality of affordances on the display.

In some embodiments, a rotatable and depressible input mechanism (e.g., 702) is a mechanical button that is rotatable, and the activation is a physical depression of the mechanical button. In some embodiments, a rotatable and depressible input mechanism (e.g., 702) is a capacitive button that is rotatable, and the activation is a touch on the capacitive button. In some embodiments, the activation (e.g., 704) does not represent a rotation of the rotatable and depressible input mechanism. In some embodiments, detection of the activation is based on detecting a press such as a physical depression or a touch and does not require a rotation for detection. For example, the device may perform an action in response to an activation of 702, and it may scroll or cycle through content or options based on the action in response to a rotation.

In some embodiments, a clock face displayed by the device includes a user interface object that indicates time. In some embodiments, the device displays an affordance based on the user interface object on the first user interface screen. For example, the affordance may be the same object as the user interface object but smaller, or it may be approximately the same object but with fewer details, to accommodate a smaller display size (i.e., since the affordance screen has a plurality of affordances, the affordance representing the user interface object may be smaller than the user interface object when displayed as part of a clock face).

In some embodiments, the user interface object and the affordance may represent a similar meaning to the user without being the same object. For example, the user interface object may be a representation of a digital clock, and the first affordance may be a representation of an analog clock. In this case, the analog clock may convey a notion of timekeeping to the user more clearly than a pair of numbers (as with a digital clock), particularly on a reduced size display. In some embodiments, the user interface object and the affordance may display the same time. In some embodiments, the user interface object and the affordance may display different times. For example, the user interface object may display a time of interest, such as a current time, whereas the affordance may display a generic time (e.g., 10:10) as an indication to the user that activating it leads to a display of the clock face. That is to say, the affordance may simply represent the idea of timekeeping to the user so that the user recognizes that activation of the affordance displays a clock face.

In some embodiments, a single press of the rotatable and depressible input mechanism acts as a back button for the device, such that a single press may return the user to the most previously displayed screen in any interface of the device.

In some embodiments, the time indicated by the user interface object is a current time. In some embodiments, the affordance indicates a current time.

In some embodiments, the user interface object is a representation of an analog clock that includes an hour hand and a minute hand. In some embodiments, the user interface object is a representation of a digital clock with a numerical indication of an hour and a numerical indication of a minute. In some embodiments, the affordance is a representation of an analog clock that includes an hour hand and a minute hand. In some embodiments, the affordance is a representation of a digital clock with a numerical indication of an hour and a numerical indication of a minute.

In some embodiments, the predetermined threshold for the first activation duration is the same as the predetermined threshold for the second activation duration. This provides a consistent threshold to the user for interactions with the device.

In some embodiments, the first activation and the second activation have an associated interval of time between them, and this interval exceeds a third predetermined threshold (e.g., 0.5 seconds, 1 second, or 2 seconds). This allows the device to distinguish between sequential single presses and a double press (described below).

In some embodiments, a rotatable and depressible input mechanism may include any of the functionalities described above in combination with one or more of the other functionalities described herein for a rotatable and depressible input mechanism. In some embodiments, device 700 may also include a button (e.g., 508) with one or more of the functionalities described herein for a button.

FIG. 8 shows exemplary button functionalities for user interfaces that may be operated on device 800. Device 800 may be device 100, 300, or 500 in some embodiments. The electronic device has a display (e.g., 504). As shown in FIG. 8 , device 800 includes rotatable and depressible input mechanism 802. The electronic device may also include a touch-sensitive surface (e.g., 504) and a button (e.g., 508).

A user may activate rotatable and depressible input mechanism 802 by activation 804. As depicted in FIG. 8 by the arrow blocks, activation 804 has a first activation and a second activation with an associated interval between the first and the second activations. In response to receiving data representing the first and second activations, the device determines whether the interval between the first and the second activations exceeds a predetermined threshold. In some embodiments, the predetermined threshold is a predetermined length of time.

In accordance with a determination that the interval does not exceed the predetermined threshold (e.g., a double press, rather than two sequential single presses), the device invokes a previously invoked application. FIG. 8 shows an application user interface screen 806 displayed by device 800 in response to double press 804 on rotatable and depressible input mechanism 802. A previously invoked application may include any application previously invoked on the device.

In some embodiments, the previously invoked application is the latest invoked application that is not currently displayed. As an illustrative example, the user may invoke a calendar application, then switch to a weather application. In this example, while the weather application is displayed, the user may invoke and display the calendar application with a double press on the rotatable and depressible input mechanism.

In some embodiments, a rotatable and depressible input mechanism (e.g., 802) is a mechanical button that is rotatable, and the first and the second activations are physical depressions of the mechanical button. In some embodiments, a rotatable and depressible input mechanism (e.g., 802) is a capacitive button that is rotatable, and the first and the second activations are touches on the capacitive button. In some embodiments, the first and the second activations (e.g., 804) do not include a rotation of the rotatable and depressible input mechanism. In some embodiments, detection of the activation is based on detecting a press such as a physical depression or a touch and does not require a rotation for detection. For example, in some embodiments, the device may invoke a previously invoked application by a double press of the rotatable and depressible input mechanism, then scroll or cycle through application content or other application data in response to a rotation of the rotatable and depressible input mechanism.

In some embodiments, the previously invoked application is invoked in an application start state. For example, in response to a double press of 802, the device may start a previously invoked application and display the application start screen, as shown in FIG. 8 . In some embodiments, the previously invoked application is invoked in a previous application state. In some embodiments, the previous application state corresponds to a state of the application after a user interaction. For example, if the user leaves the application in a particular state, then switches to another application, a double press of 802 would return the user to the particular state. If the user leaves the application on a particular screen, then switches to another application, a double press of 802 would return the user to the particular screen.

In some embodiments, the previously invoked application is invoked in a stored application state. For example, the user may save a particular state of an application and return to the state through a double press of 802.

In some embodiments, a rotatable and depressible input mechanism may include any of the functionalities described above in combination with one or more of the other functionalities described herein for a rotatable and depressible input mechanism. In some embodiments, device 800 may also include a button (e.g., 508) with one or more of the functionalities described herein for a button.

FIG. 9 shows exemplary button functionalities for user interfaces that may be operated on device 900. Device 900 may be device 100, 300, or 500 in some embodiments. The electronic device has a display (e.g., 504). As shown in FIG. 9 , device 900 includes button 902. The electronic device may also include a touch-sensitive surface (e.g., 504) and a rotatable and depressible input mechanism (e.g., 506, 602, 702, or 802).

A user may activate button 902 by activation 904. As depicted in FIG. 9 by the arrow block, activation 904 has an associated activation duration. In response to receiving data representing the activation, the device determines whether the activation duration exceeds a predetermined threshold. In some embodiments, the predetermined threshold is a predetermined length of time.

In accordance with a determination that the activation duration does not exceed the predetermined threshold (e.g., the input is a single press of button 902, as depicted by the short, single arrow block shown for activation 904), the device displays a user interface screen that includes at least a first affordance indicating a contact from a designated list of one or more contacts, wherein the designated list is a subset of a full list of contacts on the electronic device. For example, FIG. 9 shows user interface screen 906 that includes several affordances indicating contacts, such as affordance 908 that indicates a contact “Katie.” Contacts may be indicated by a text such as a name or an image (e.g., a user- or system-designated image associated with the contact or with a contact entry for the contact).

In some embodiments, a button (e.g., 902) is a mechanical button, and the activation is a physical depression of the mechanical button. In some embodiments, a button (e.g., 902) is a capacitive button, and the activation is a touch on the capacitive button.

In some embodiments, the designated list of contacts is different from other sets of contacts, such as VIPs (very important persons) or favorites. For example, in some embodiments, the designated list of contacts may be contacts with whom the user has an emotional connection. This functionality provides methods of communicating with these designated contacts (described below) that are more informal, intimate, and/or frequent than those used for other sets of contacts like VIPs, which may be a more practical set of contacts and means of communication (e.g., email). By providing these functionalities of communicating with contacts with whom the user is emotionally connected, the connection between the device and the user is strengthened and extends beyond purely productivity- or work-related functions.

This button functionality allows the user to quickly access a user interface screen that includes affordance(s) indicating contact(s) from a designated list of one or more contacts. It is to be noted that, in some embodiments, this screen is accessed by a single press on the button, similar to the single press on the rotatable and depressible input mechanism, which in some embodiments allows the user to access a user interface screen that includes a plurality of affordances representing application(s). These parallel functionalities enhance the usability and intuitive feel of the device by providing access to conceptual similar functionalities (e.g., a designated contacts “home screen” and an applications “home screen”) through similar types of inputs (e.g., a single press on the button and a single press on the rotatable and depressible input mechanism).

In some embodiments, the designated list of contacts is based on at least one of the following: time of day of interactions between the user and a contact (e.g., designated contacts may have more interactions with the user outside of typical weekday working hours relative to other contacts), frequency of interactions between the user and a contact (e.g., designated contacts may have an increased frequency of interactions with the user relative to other contacts), and length of interactions between the user and a contact (e.g., designated contacts may have longer interactions with the user relative to other contacts).

In some embodiments, the designated list of contacts is user-designated. For example, the device may provide a selection interface for the user to select contacts for the designated list of contacts.

In some embodiments, while the user interface screen is displayed, the device may receive second data representing a touch (e.g., a single press) on the touch-sensitive display at the location of an affordance corresponding to a contact. In response to receiving the second data, the device invokes a user prompt for selecting an application configured to provide a mode of interaction with the contact.

In some embodiments, the application configured to provide a mode of interaction with the contact is a text messaging application for sending a text to the contact. Advantageously, this functionality allows the user to quickly send a text to a designated contact without needing to enter a text messaging interface and then select the designated contact, allowing the user to interact with a designated contact more easily. In some embodiments, the application configured to provide a mode of interaction with the contact is a low-latency asynchronous voice communication application for opening low-latency asynchronous voice communication with the contact. In some embodiments, the application configured to provide a mode of interaction with the contact is an application for sending a drawing to a contact.

This button functionality allows the user to select a designated contact, then select a mode of interaction, rather than selecting the mode of interaction (e.g., by opening an application), then selecting the contact. Advantageously, this makes it easier for the user to interact with a contact, e.g., a contact with whom the user may frequently interact or with whom the user may be more eager to interact. That is to say, this functionality may improve the user interface with the device by allowing the user to prioritize a particular contact through quicker access to the contact, rather than forcing the user to first select the specific application for the interaction.

In some embodiments, while the user interface screen is displayed, the device receives third data representing a second touch on the touch-sensitive display at the location of a portion representing a contact and a third touch on the touch-sensitive display at the location of a portion representing a contact. The second and third touches are separated by an associated duration interval. In response to detecting the touches, the device determines whether the duration interval is less than a predetermined duration, and in accordance with a determination that the duration interval is less than the predetermined duration (e.g., a double touch on the portion representing the contact), the device provides an interface configured to receive data representing a user input and send a signal to a second electronic device. For example, in some embodiments, a user viewing the user interface screen may activate a display of a contact with a single tap to provide a mode of interaction with the contact (as described above), or the user may activate a display of a contact with a single tap to enter the interface.

The signal represents an instruction instructing the second electronic device to generate a haptic alert based on the data. In some embodiments, the user input represented by the data includes a touch on the touch-sensitive display. For example, if the data represent a series of touches on the display in a particular pattern, the haptic alert generated could be based on the particular pattern of touches. Therefore, this interface provides a way for the user to send a customizable haptic alert to a designated contact. This further reinforces the idea that the designated contacts are contacts with whom the user has an emotional connection by allowing the user to send a tangible message to the contact, even if the user and the contact are apart.

Attention is now directed to FIG. 10 , which shows exemplary button functionalities for user interfaces that may be operated on device 1000. Device 1000 may be device 100, 300, or 500 in some embodiments. The electronic device has a display (e.g., 504). As shown in FIG. 10 , device 1000 includes button 1002. The electronic device may also include a touch-sensitive surface (e.g., 504) and a rotatable and depressible input mechanism (e.g., 506, 602, 702, or 802).

As described above, in accordance with a determination that an activation of the button is a single press, the device displays a user interface screen that includes at least a first affordance indicating a contact from a designated list of one or more contacts. In some embodiments, in accordance with a determination that the activation duration of the button activation exceeds the predetermined threshold (e.g., an extended press on the button), the device substitutes the user interface screen with a second user interface screen that includes an affordance representing a user prompt to power off the electronic device.

For example, as depicted in FIG. 10 , a user may activate button 1002 by activation 1004. As depicted by the long arrow block, activation 1004 is an extended press of button 1002. In response to receiving data representing activation 1004, the device displays user interface screen 1006, which includes affordance 1008. Affordance 1008 represents a user prompt to power off the electronic device. A user may tap, swipe, or otherwise activate affordance 1008 to power off the electronic device.

In some embodiments, screen 1006 also includes an affordance representing a user prompt to enter a power-saving mode of the electronic device (e.g., affordance 1010). In some embodiments, power-saving mode includes altering the device display (e.g., altering the color and/or brightness of one or more pixels) to reduce power consumption. In some embodiments, power-saving mode includes altering the function of one or more device components to reduce power consumption. For example, the device may alter or reduce the function of one or more RF circuitry components (such as wireless transceivers, Wi-Fi components, Bluetooth components, or other components that send and receive signals to and from external devices or servers), speakers, GPS sensor, accelerometer, directional sensor, gyroscope, motion sensor and/or other components of the device that consume power. In some embodiments, power consumption refers to battery power consumption. A user may tap, swipe, or otherwise activate affordance 1010 to enter a power-saving mode of the electronic device.

In some embodiments, screen 1006 also includes an affordance representing a user prompt to turn off the touch-sensitive display (e.g., affordance 1012). A user may tap, swipe, or otherwise activate affordance 1012 to turn off the touch-sensitive display.

In any of the embodiments described herein, the device may turn on the display in response to a user movement of the device (e.g., a wrist raise, lifting and/or rotation of the device, or any other indication that the user has moved the position of the device for viewing the display). As described above, the device may include various sensors, such as accelerometer 534, gyroscope 536, and motion sensor 538, that may allow the device to detect a user movement of the device. These can be operatively connected to I/O section 514, which could send a signal to the display to turn on the display. The device may also be configured to use these components to control turning off the display. In some embodiments, a lack of a specific motion input for a predetermined duration of time may cause the device to turn off the display.

In addition to any of these functionalities, allowing the user to further control the display through affordance 1012 is advantageous because some users may not be as capable of generating specific movements of the device configured to turn on or turn off the display. For example, if the user has interacts with or wears the device on a prosthetic limb, or uses a prosthetic limb to hold the device, the movements of the prosthetic limb may not generate the same types of movement that the device is configured to detect. Advantageously, this functionality makes the device more usable for disabled users and increases compliance with, e.g., the Americans with Disabilities Act.

In some embodiments, the device may be configured to detect the intensity of touches. This functionality is described in greater detail, for example, in reference to touchscreen 504 above. Techniques for detecting and processing touch intensity may be found, for example, in related applications: International Patent Application Serial No. PCT/US2013/040061, entitled “Device, Method, and Graphical User Interface for Displaying User Interface Objects Corresponding to an Application,” filed May 8, 2013 and International Patent Application Serial No. PCT/US2013/069483, entitled “Device, Method, and Graphical User Interface for Transitioning Between Touch Input to Display Output Relationships,” filed Nov. 11, 2013.

In some embodiments, while user interface screen 1006 is displayed, device 1000 detects a first touch on the touch-sensitive display with a first characteristic intensity. In response to detecting the first touch, the device determines whether the first characteristic intensity is above an intensity threshold. In response to a determination that the first characteristic intensity is above the intensity threshold, the device executes a separate function of the electronic device. As used here, a “separate function” of the electronic device may refer to any device function not specifically ascribed to a rotatable and depressible input mechanism interaction or a button interaction described herein.

In some embodiments, when the device is powered off when the extended press of the button is received, and in accordance with a determination that the activation duration of the button activation exceeds the predetermined threshold (e.g., an extended press on the button), the device powers on. As described above, an extended press on the button may serve to power on or power off the device, depending on the state of the device when the button activation is detected.

In some embodiments, a button may include any of the functionalities described above in combination with one or more of the other functionalities described herein for a button. In some embodiments, device 900 and/or device 1000 may also include a rotatable and depressible input mechanism (e.g., 506, 602, 702, or 802) with one or more of the functionalities described herein for a rotatable and depressible input mechanism.

FIG. 11 shows exemplary button functionalities for user interfaces that may be operated on device 1100. Device 1100 may be device 100, 300, or 500 in some embodiments. The electronic device has a display (e.g., 504). As shown in FIG. 11 , device 1100 includes button 1102. The electronic device may also include a touch-sensitive surface (e.g., 504) and a rotatable and depressible input mechanism (e.g., 506, 602, 702, or 802).

A user may activate button 1102 by activation 1104. As depicted in FIG. 11 by the arrow blocks, activation 1104 has a first activation and a second activation with an associated interval between the first and the second activations. In response to receiving data representing the first and second activations, the device determines whether the interval between the first and the second activations exceeds a predetermined threshold. In some embodiments, the predetermined threshold is a predetermined length of time.

In accordance with a determination that the interval does not exceed the predetermined threshold (e.g., a double press, rather than two sequential single presses), the device invokes a payments application. Further descriptions of exemplary payments applications may be found, for example in the related application U.S. Application Ser. No. 62/004,886, entitled “User Interface for Payments,” filed May 29, 2014.

FIG. 11 shows a payments application user interface screen displayed by device 1100 in response to double press 1104 on button 1102. In some embodiments, invoking an application (e.g., a payments application) may include invoking and/or displaying an application that is already running. In some embodiments, double press 1104 may invoke a different state or screen of an already running and/or displayed application.

In some embodiments, the button (e.g., 1102) is a mechanical button, and both of the first and the second activations represent depressions of the mechanical button. In some embodiments, the button (e.g., 1102) is a capacitive button, and both of the first and the second activations represent touches on the capacitive button.

In some embodiments, the device displays a user interface screen that includes an affordance representing a mode of payment. In some embodiments, the mode of payment is a credit card. In some embodiments, the affordance depicts a visual representation of the face of the credit card, indicating a credit card number and a credit card company. As shown in FIG. 11 , device 1100 displays affordance 1106, which represents a credit card. The credit card itself is indicated by the displayed credit card company name 1108 and the displayed credit card number 1110. In some embodiments, the credit card company and credit card number correspond to a user's credit card account.

In some embodiments, the mode of payment is a debit card. In some embodiments, the affordance depicts a visual representation of the face of the debit card, indicating a debit card number and a debit card bank. In some embodiments, the debit card bank and debit card number correspond to a user's debit account.

In some embodiments, the mode of payment is a bank account. In some embodiments, the affordance indicates at least one of a bank associated with the bank account, a type of the bank account, and a bank account number associated with the bank account. In some embodiments, the bank account is a checking account. In some embodiments, the bank account is a savings account.

This functionality allows the user to quickly invoke a payments application through an input (e.g., a double press of the button). It is to be noted that, in some embodiments, this application is invoked by a double press on the button, similar to the double press on the rotatable and depressible input mechanism, which in some embodiments allows the user to invoke a previously invoked application. These parallel functionalities enhance the usability and intuitive feel of the device by providing access to conceptual similar functionalities (e.g., applications) through similar types of inputs (e.g., a double press on the button and a double press on the rotatable and depressible input mechanism).

In some embodiments, a button may include any of the functionalities described above in combination with one or more of the other functionalities described herein for a button. In some embodiments, device 1100 may also include a rotatable and depressible input mechanism (e.g., 506, 602, 702, or 802) with one or more of the functionalities described herein for a rotatable and depressible input mechanism.

FIG. 12 shows exemplary button functionalities for user interfaces that may be operated on device 1200. Device 1200 may be device 100, 300, or 500 in some embodiments. The electronic device has a display (e.g., 504). As shown in FIG. 12 , device 1200 includes button 1202 and rotatable and depressible input mechanism 1204. The electronic device may also include a touch-sensitive surface (e.g., 504).

A user may activate button 1202 and rotatable and depressible input mechanism 1204 by activations 1206 and 1208, respectively. Activation 1206 has a first associated activation duration, and activation 1208 has a second associated activation duration. As depicted in FIG. 12 , activations 1206 and 1208 are received substantially simultaneously, such that activation 1208 overlaps with activation 1206 for an overlap interval.

In response to receiving the data, the device determines whether the data meet predetermined criteria. In accordance with a determination that the data meet the predetermined criteria, the device reboots. In some embodiments, the reboot is a hard reboot. In some embodiments, the reboot is a soft reboot.

In some embodiments, the rotatable and depressible input mechanism (e.g., 1204) is a mechanical button that is rotatable, and the activation of the rotatable and depressible input mechanism includes a depression of the mechanical button. In some embodiments, the rotatable and depressible input mechanism (e.g., 1204) is a capacitive button that is rotatable, and the activation of the rotatable and depressible input mechanism includes a touch on the capacitive button. In some embodiments, the activation of the rotatable and depressible input mechanism (e.g., 1208) does not include a rotation of the rotatable and depressible input mechanism. In some embodiments, detection of the activation is based on detecting a press such as a physical depression or a touch and does not require a rotation for detection.
